The City of Oxford now has I discover, not one, but two jazz promoters called Max. One of the guiding spirits behind the Oxford Jazz Festival is a good friend of LondonJazz,  Max Mason. Now enter Max Richardson, who is starting up a new series this Saturday at the Jam Factory in Park End Street with a gig featuring singer-pianist  Theo Jackson and pianist Reuben James. (who absolutely shone as the late Abram Wilson’s pianist.) Good luck, and put it up to eleven, Max.
